Have you considered just BIOS flashing the cards?
Never considered it, but these are asustek 5850s, so they don't have the bios switch. I'm little shy of flashing the BIOS and bricking them.
I though that having amd overdrive auto-start would be simplist answer. Computer boots, loads amd overdrive, overclock set, rig starts mineing.
Is there something I'm not seeing?
